Abstract:     A magnetohydrodynamic device having a duct for a conducting gas to flow at an angle with the direction of the magnetic field induction vector. The duct is situated in the magnetic system and is provided with a plurality of electrodes adapted to interact electrically with the gas, whereas the cross-sectional shape of the duct working space is bounded by a closed contour formed by a curve inscribed into a rectangle having its sides a>/=b, while the minimum radius R of curvature of said curve is related to the distance x from the entry to the duct for the conducting gas to flow, to the cross-section under consideration by the following formula: <IMAGE> where Po and So stand, respectively, for the perimeter and cross-sectional area of the duct 1 at the entry thereof, and 0.5</= alpha </=1.

Claim What is claimed is:     1. A magnetohydrodynamic device, comprising: a magnetic system; a duct located in said magnetic system and adapted for a conducting gas to flow at an angle with the direction of the induction vector of said magnetic field; a plurality of electrodes electrically interacting with said gas; a cross-sectional shape of the working space of said duct bounded by a convex curve inscribed into a rectangle with its sides a<= b; a minimum radius R of curvature of said curve being related to a distance `x` from entry of said duct to the cross-section under consideration by the following formula: [Figure] where Po and So stand, respectively, for the perimeter and cross-sectional area of the duct at the entry thereof and 0.5<=α<=1.
